Diverse Energy Sources Provide Reliable, Affordable Electricity

America’s electric companies rely on a variety of domestic fuels to generate electricity. Fuel diversity helps to protect electric companies and their customers from contingencies such as fuel unavailability, fuel price fluctuations, and changes in regulatory practices that can drive up the cost of a particular fuel. Fuel diversity also helps to ensure stability and reliability in electricity supply and strengthens national security.

Our Nation’s Energy Mix

No individual fuel is capable of providing the energy to meet all of our nation’s electricity demands, which is exactly why it’s necessary to utilize all the resources available to us. In 2012:

  • Coal provided 37.4 of our nation’s electricity;
  • Natural gas supplied 30.3 percent;
  • Nuclear generation produced 19 percent;
  • Hydro provided 6.7 percent of the supply;
  • Non-hydro renewables produced 5.4 percent; and
  • Fuel oil provided 0.6 percent of the generation mix.

Energy Strategy

The electricity generation mix differs from state to state and region to region, depending on the availability and cost of fuels located there. Major changes in the generation mix can have economic impacts, especially on a regional basis.
